1932, Serial No. 586,383

2 Claims. (01. 229-7) The object of this invention is to provide a papercontainer suitable for use in cafeterias and elsewhere for containingmilk, orange juice, or other drink, and from which the liquid is to bewithdrawn through a straw.

The improved container is illustrated in Fig. 1 of the accompanyingdrawing, while Fig. 2 shows the blank from which the body po'rtionorside wall thereof may be made. Figs. 3, 4 and 5 show modifications inthe method of carrying out the invention. Fig. 6 is a detail sectionalview on a larger scale of one comer of the container.

Referring to Fig. 2 it will be seen that the blank I is mainly of thecurved shape necessary 5 for the formation of a conical container, andis of such a size that when rolled up it will form a double-walled body.The part 2 thereof to the left of the broken line A forms the inner plyof the side wall, while the part 3 to.the right of such line forms theouter ply. In a suitable position in the irmer portion 2 of such blank ahole 4 is formed larged enough for the easy insertion of a straw, and atthe outside edge of the part 3 perforations or weakening lines 5 areformed in such a position that when the blank is. rolled up to form aconical body of the container the part enclosed by such perforationsorweakening lines will lie over and close the hole 4,

as shown in Fig. 1. A tab or extension 6 is 30. preferably formed at theedge of the blank I, for the purpose hereinafter described.

In the process of manufacture of the improved container the blank I isfirst rolled up into conical form and secured by a. suitable adhesive,35 very little if any of the latter being applied to the part of theblank between the perforations or weakening lines 5.

For the closure at the smaller end of the container it is preferred toemploy a flanged disc I, 10 and to secure same in the body by rollingthe edge of the latter over into contact with the flange of such discand continuing the rolling operation so that both flange and body" arerolled together. The closure'l mayhowever be secured in position in anyother desired manner.

It is intended that the container thus formed.

with a closure at its smaller end shall then be treated with paraflinwax or other suitable substance for waterproofing and sterilizing it,this treatment being relied on to give sufficient adhesion to the partbetween the weakening lines '5 to maintain a suitable covering over thehole 4 in the inner ply of the side wall and prevent leakage of thecontents of the container therethrough. e

The container is to be fllled with its larger end uppermost, and, afterfilling, the closure at such larger end is to be inserted. Suchv closureis also preferably in the form of a flanged disc 8, and is to beinserted into the body until it 5 comes in contact with a shoulder 9formed in the latter, and the edge of the body is then preferably rolleddown onto the flange and the rolling continued including such flange, inthe same way as at the other end.

The container thus filled and completed is delivered with its smallerend at the top'as shown in Fig. 1, and when it is desired to open sameto partake of the contents the tab 6 is grasped and the part between theweakening lines 5 can then 15 be easily turned back to expose the hole4, through which a straw can be inserted for drawing off the contents.

- If desired the rows of perforations or weakening lines 5 may be joinedat their inner ends, as 20 shown in broken lines in Fig. 2, so that thepart thus surrounded can' then be entirely removed.

In some cases it may be preferred to insert the straw through one of theend closures instead of through the side wall of the container, and toen- 5 able this to be effected arrangements such as are shown in Figs.3, 4 and 5 may be adopted.

In Fig. 3 the end closure is formed of two layers of material, in theinner of which (when in position in the container) a hole 4 is formed,while in the outer layer perforations orweakening lines 5 are formed,the arrangement being therefore substantially the same as that shown inFigs. 1 and 2. The-two layers are secured together in any suitablemanner and as in the form shown-in Figs. 1 and 2 the treatment withparaifin wax or thelike may be relied on to give suificient adhesion .tothe part which is to be raised to uncover the hole. f

A similar result may be obtained by the means shown in Fig. 4, in whichinstead of forming theend closure of two layers of material it is formedof one only, a hole 4 being made therein as in the other arrangements.This hole is to be covered by a separate piece of material, .as III,which is secured to the closure by means of adhesive applied to the partlshown shaded in Fig. l the remaining portion (which constitutes a tabby means of which the piece Hi can be lifted and removed to uncover thehole) being left free from 5 adhesive the treatment with paraffin wax orthe like being again depended upon to hold such unpasted part downsufliciently well for the purpose until it is desired to gain access tothe contents I of the container.

Fig. 5 illustrates a further modification, in which the end closure isagain formed of a single layer of material. 'In this case the hole 4 isto be punched only about half way through the thickness of the material,from the underside, while the weakening lines or perforations 5 arepunched also half way through the material but from the upper side. Withthis arrangement the container can be easily opened by raising the partenclosed by the half out through weakening line'5 at the point II, whensuch enclosed part will in rising take with it the part closing the hole4, and so afford access to the contents.

What I claim as my invention, and desire to secure by patent, is:-

1. A paper container comprising a tubular body having its wall composedof an inner layer and an outer layer, said layers being formed from alongitudinally curved blank and being continuous from end to end of theblank, said inner layer having an opening near the center of said blankconstituting the point of junction between the inner and outer layers,and said outer layer in the portion thereof which covers said openinghaving weakened lines defining sides of a. tab to uncover said opening,said tab extending to the exposed end of said outer layer.

2. A paper container comprising a tubular body having its wall composedof an inner layer and an outer layer, said layers being formed from ablank of the curved shape necessary for the formation of a conicalcontainer, said inner layer having an opening near the center of saidblank constituting the point of junction between the inner and outerlayers, and said outer layer in the portion thereof which covers saidopening having weakened lines defining sides of a tab to uncover saidopening, said tab extending to the exposed end of said outer layer.
